Preheat your oven to 220 °C top/bottom heat and line your baking sheet with baking paper. Wash your cauliflower well under running water. Dry it off well. Now carefully separate small florets.
Mix all the ingredients for the breading in a bowl with a fork until all the blobs have dissolved. You may help with a blender.
Dip the cauliflower florets in the breading, let them drain briefly and place them on your baking sheet. The breading should be enough for all the florets. Bake them for 10 minutes at 220 °C, then turn them and bake them for another 10 minutes.
Prepare the marinade and BBQ sauce
In the meantime, mix all the ingredients for the barbecue sauce in a small saucepan, bring it to a boil, let it simmer over medium heat for about 8-10 minutes and then take it off the stove.
Once your florets have been baked for 20 minutes, brush them with about 1/2 of the BBQ sauce - if possible on all sides, and let them bake for another 20 minutes. Once your cauliflower wings are baked, you can serve them with the remaining half of the BBQ-sauce and enjoy them to to the fullest!
